With Sully into the Sioux Land

In Short

With Sully into the Sioux Land follows young Al Briscoe after a frontier raid claims his father, displaces his family, and leaves his little brother Tommy a captive among the Sioux. Determined to track the boy down, Al secures a civilian clerkship on General Alfred Sully’s staff during the United States Army’s 1864 expedition into Dakota Territory. Marching across the northern plains, surviving riverboat ambush, and witnessing the brutal clashes at Killdeer Mountain and the Bad Lands, Al searches for his brother while earning the respect of veteran soldiers, ultimate resolution of his family's plight, and a path toward his own future.

The Story

The narrative opens upon a peaceful Minnesota farmstead suddenly shattered by the Dakota Uprising of 1862. Young Al Briscoe witnesses the sudden assault on his family’s claim, where his father is slain in the yard and his little brother, Tommy, is carried away into captivity by a warrior bearing a distinctive facial scar. Al manages to shepherd his mother and sister Annie to safety in the reeds before fleeing to Fort Ridgely. There, Al and his companion Wallace Smith endure the terrifying siege of the post. Stripped of their home and all possessions, the destitute Briscoes relocate to St. Louis, Missouri, where Al seeks employment to support his surviving family while never relinquishing hope of finding Tommy.

In St. Louis, Al follows the military preparations under General Alfred Sully, who is organizing a massive penal campaign to march up the Missouri River into the Dakota wilderness. Rumors persist on the border that the hostiles hold white captives. Driven by his double objective of assisting the Union forces and finding Tommy, Al secures a post in the quartermaster's department. Travelling aboard river transports up the Missouri River, Al becomes an unofficial aide to General Sully and earns the camaraderie of the Dakota Cavalry—nicknamed the "Coyotes"—after distinguishing himself during skirmishes and buffalo hunts.

As Sully’s twenty-two hundred troops march deep into uncharted territory, they encounter the massed encampment of Sioux warriors at the Battle of Tahkahokuty (Killdeer Mountain). Amid the roaring artillery and desperate charges, Al comes face to face with Te-o-kun-ko, the scarred warrior who had abducted his brother. Though the Indian escapes into the rugged heights, the confrontation confirms Al's pursuit. The army presses onward, suffering severe privation while carving a path through the labyrinthine Bad Lands under constant harassment from hostile snipers. Shortly thereafter, Al encounters Te-o-kun-ko once again under unexpected circumstances; the warrior reveals that Tommy is no longer with his band, having been traded to white river merchants at Fort La Framboise.

Advised by General Sully to head downriver to locate his brother, Al travels back toward civilization. His return journey is fraught with peril: he survives a deadly Indian ambush in the Painted Woods while working a riverboat yawl, and later, while navigating Missouri on his way to St. Louis, his party is captured by Confederate guerillas under the command of Yeager. Al shows remarkable grit under threat of execution until a sympathetic guerrilla intervenes. Rescued after the dramatic defense of Glasgow, Al returns to St. Louis to find his family safe and happily discovers that Tommy has indeed been recovered by traders and restored to his mother. With his brother returned, his family's property sold to advantage, and glowing recommendations from General Sully, Al secures an appointment to the United States Military Academy at West Point.

In Its Own Voice

"He threw himself in a paroxysm of grief beside his father's body, crying out to him and vainly striving to discover a sign of life in the quiet face, already grown so peaceful under the soothing touch of death."

"If you will untie my hands and leave me free to use them," said he, "I will hand you my shoes,--and something more."
